Question

Draw a tangent to the circle from the point B, having radius 3.4 cm, and centre'C'.
Point B is at a distance 8.1 cm from the centre.​

Answer 1

Step-by-step explanation:

first construct a circle taking pair of passes with radius 3.4cm

Then taking the centre of the circle as one unit measure 8.1 cm and draw a line.

Then again point your compass on C (centre) and stretch the pencil ,a little more than half of the mid point of 8.1 and mark and do the same for B.

Then draw a line passing through the markings and take the point intersecting line CB as your centre and then point your compass on that centre and stretch the pencil to C ( which wil be your radius ) and draw a circle.

Then draw a line from Point B to the point where your circles meet.
